摘要 本文提出了一种新的动态频率选择 (DFS)算法 ,它适用于无线局域网 /无线个域网 (WLAN/WPAN)等小区域无线多媒体通信系统 .文章给出了算法处理过程的描述 ,并以HIPERLAN/2系统为例进行了仿真 .仿真结果表明 ,与目前已有的算法相比较 ,新算法具有干扰探测快、跳转换频稳定等特点 ,能够在复杂传播环境下提高WLAN/WPAN的服务质量 (QoS) .该算法已被成功地应用于所研制的HIPERLAN/2系统中 . This paper brings forward a new DFS algorithm utilized in WLAN/WPAN and gives the disposition processing.As a material application example,the paper simulates the algorithm in HIPERLAN/2.Compared to other algorithm,the result of simulation indicates that the new algorithm has these characteristics such as fast finding interference and steady changing frequency.The algorithm can satesfy request of WLAN/WPAN in complex communications environment and ensure Quality of Service (QoS) of systme.It has been used successfully in the HIPERLAN/2 system developed.
